Inside the 6 most fascinating, innovative reconstruction projects in NYC
One Madison, Penn Plaza and the Terminal Warehouse
It's often cheaper to rip it up and start again. But a handful of NYC's best new buildings are preservation and reconstruction jobs.

The rat’s nest of regs that is city zoning may stymie construction, redevelopment and conversion projects — but in the hands of the right visionary architects and engineers, zoning can also produce truly innovative outcomes.

Here’s a look at some of NYC’s most fascinating extreme makeovers making their debuts right now.

The big deal

To reinvent One Madison in Midtown South, SL Green Realty Corp. took the limestone building that stretched along the north side of 23rd Street from Madison to Park avenues and added 520,000 square feet of new, glass-enclosed offices. It now totals 1.4 million square feet.

Footings were enlarged by 200%, 13 columns were added and existing ones reinforced. Every core, every elevator shaft and every fire stair was demolished while carving out 12% of the floors so a new core could be shifted north.

“It would have been easier to tear it down, but we made the conscious decision to retain the nine floors of the original limestone and fit it into the architectural context of the neighborhood,” said Steve Durels of SL Green.

Learning from One Vanderbilt, the amenities and hospitality programming were geared toward the home-away-from-home environment that tenants desire. The building has 1.2 acres of outdoor space including a rooftop restaurant designed by David Rockwell. A 54,000-square-foot Chelsea Piers fitness center will be open to the public, while along East 23rd Street, new dining options will deliver both upscale and affordable offerings.

IBM and Franklin Templeton have leased about 330,000 square feet each with Triple Seven, Palo Alto Networks and others filling all the tower floors. Asking rents were $170 to $180 per foot in the tower and $115 per foot in the base.

The strip show

Vornado Realty Corp. has reinvented the Penn Plaza area with both Penn 1 and now Penn 2.

It’s an extreme makeover of Seventh Avenue next to Madison Square Garden designed by MdeAS Architects. A rectangle structure was stripped and refitted with a new, multi-story glass “bustle” across its front held up by giant angled footings and a new, triple-glazed glass wall.

“It’s all brand-new construction attached to the existing property,” said Glen Weiss of Vornado.

The lower 12 floors have setbacks with outdoor spaces and every other upper story has loggias on the western corners. The northern end of the bustle on the second floor has a 280-seat, 4,000 square-foot town hall with large screens, a green room and terrace. “It’s a place where our tenants can do anything,” Weiss said.

The property is topped with a 17,582-square-foot outdoor park and pavilion.
